Abstract: A method for discovering the topology of a connected lighting system. The method comprises: receiving a first measurement of a first light source in relation to a first sensor; receiving a second measurement of the first light source in relation to a second sensor; generating a first estimate of the position of the first light source, based on a first angle at the first sensor between (i) a first direction toward a current light source position and (ii) a second direction defined by the first measurement; generating a second estimate of the position of the first light source, based on a second angle at the second sensor between (i) a third direction toward the current light source position and (ii) a fourth direction defined by the second measurement; and generating an updated light source position of the first light source based on the first and second estimates.

Abstract: A configurable light sensor comprising an array of photocells. The light sensor measures ambient light reflected from a surface in area to be monitored. A lens directs the light onto the array of photocells. A microcontroller reads each individual photocell and processes the signals from the photocells according to one or more of the methods disclosed herein. The light sensor is configurable in that the area that monitored by the light sensor is customized to match the area lit by an associated light source. The configuring process defines an active area to be monitored, by determining which subset of photocells in the array, referred to as the active set of photocells, corresponds to the area being illuminated by the light fixture. The light sensor is subsequently able to monitor the defined active area and to report sensor output values based on measurements made from the photocells monitoring the active area.
